1 Claim.

This invention relates generally to throttle controls for internalcombustion engines with special reference to the type employed on landtraveling vehicles.

The main object of this invention is to provide an improved form ofconstruction including the working principles involved in my UnitedStates Patent No. 1,819,111.

This, and other objects, will become more apparent from thespecification following as illustrated in the accompanying drawing, inwhich:

Fig. 1 is a plan showing the control and associated parts.

Fig. 2 is a side elevation of the form of the device shown in Fig. 1.

Fig. 3 is a section taken along the line 3-3 in Fig. 2.

Fig. 4 is a section taken along the line l4i in Fig. 1.

Fig. 5 is a section taken along the line 55 in Fig. 1.

Fig. 6 is a side elevation of an alternative form of the device.

Fig. 7 is a section taken along the line 7-7 in Fig. 6.

Similar numbers of reference refer to similar parts throughout theseveral views.

Referring in detail to the drawing, there is shown in Figs. 1 and 2 atubular gear shift lever 10 whose uppermost end 11 has a somewhatreduced internal diameter which provides a bearing for an internal rockshaft 12 on whose upper end is secured a handle 13 similar to those nowemployed on gear shift levers. The lower end 14 of the gear shift lever10 is curved and one side thereof forms a bearing for the lower end 15of the rock shaft 12, to which is hingedly attached the square tubularend 16 of a telescopic shaft section whose remaining portion is a squarerod 1'7 which fits slidably within the tubular portion 16. The rod 17has its outermost end hingedly attached to the short shaft 18, whichjournals in the floor board 19.

The lever 20 is secured on the shaft 18 on the under side of the floorboard 19 and is joined by a connecting rod 21 to a bell crank lever 22which is mounted on a standard 23. The opposite side of the bell cranklever 22 is provided with an offset push rod 24 whose end 25 passesslidably through the clamp 26, which is secured to the usual footoperated throttle control rod 27. Appropriate adjustments are of courseprovided in order to enable the device to be adapted to any type ofmotor car. For example, it is desirable to provide the bell crank lever22 with a plurality of holes 28 along its several arms in order to varythe relative movements between the handle 13 and the push rod 24.

In the operation of this device a rotary movement applied to the handle13 will produce a slid- 0 ing movement of the push rod 24 and as soon asthe off-set 29 of the rod 24 comes in contact with the clamp 26 itbegins to operate the throttle control rod 27. It will be understood, ofcourse, that the end 25 of the rod 24 slides freely within the clamp 26.

In the form of the device shown in Figs. 6 and 7 the shaft 12 is notplaced within the gear shift lever 30 but journals in the bearings 31,which are in the form of brackets 32 which are secured around the upperand lower ends of the lever 30 by means of the countersunk set screws33. The remaining portions of this form of the device are identical withthose previously described.

The operation of both forms of this device are identical with that in myprevious patent before referred to, and consists, briefly, incontrolling the throttle manually by means of the same hand whichoperates the gear shift lever. In other words, if a car is standing on ahill and is being held by the foot brake it is obvious that the operatorcannot operate the foot throttle since his right foot is alreadyoccupied in holding the foot brake.

With my device his right hand, which is occupied in placing the gearshift lever in an intermediate or low gear position, can simultaneouslyspeed up the engine in order that it can take care of the additionalload about to be imposed thereon as soon as the clutch is brought intoengagement.

I claim:

The combination of a gear shift lever of the type having a ball andsocket support above it which may be moved in a plurality of planes, arigid rock shaft mounted within said lever and having the gear shiftlever handle secured to its upper end, a rotatable shaft connectionthrough the footboard of an automobile including operating connectionsto the gas throttle, and a double universal connection between saidrotatable shaft and said rock shaft including an extensible connectionbetween the ends of said double universal connection.
